Pros & Cons

Stack AI

  • Free tier to test
  • Enterprise-grade security
  • No markup on model costs
  • No public self-serve paid plans
  • Acquisition report unverified
  • Enterprise pricing is opaque

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
